Description
Technical field
The utility model is related to a kind of positioner of rolled thread, specifically, is related to a kind of applied to rolled thread
Flexible positioning device.
Background technology
The positioning of branch piece is the conventional positioning means of rolled thread.The purpose positioned using branch piece is workpiece is held in one
Ad-hoc location scope, it is ensured that workpiece smoothly shapes, meets corresponding requirements.
At present, rolled thread uses rigid branch piece to position, i.e., the position of the locating surface of rigid branch piece positioning is fixed
, in initial manufacture, workpiece axial line is only completed not in the plane that two cylindrical die roll axial lines are constituted in component shaping,
Major Diam is not when growing up, and the axial line of workpiece is just in the plane that two cylindrical die roll axial lines are constituted.
The content of the invention
The utility model is arranged on branch piece on the sliding seat of the branch bar of scalable motion, then branch bar is fixed into peace
In frame.
The height change of branch piece locating surface is specially controlled, remains that the axial line of workpiece is always positioned at cylindrical die roll axle center
In line plane.
Technical scheme
A kind of flexible positioning device of rolled thread, including branch bar fixed seat (2), screw-rolling machine frame (7), in addition to branch
Bar sliding seat (1), connecting rod (3), Electrohydraulic servo cylinder；Branch bar is designed and fabricated as branch bar fixed seat (2) and branch bar
Sliding seat (1), branch bar sliding seat (1) is used to install branch piece and produces movement in vertical direction, branch bar with branch piece fixed seat (2)
Fixed seat (2) is used to fix branch piece in screw-rolling machine frame (7), it is ensured that the movement in vertical direction of branch bar sliding seat (1)；Branch piece
Seat sliding seat (1) is provided with branch piece installation site and fastener；Branch bar fixed seat (2) provided with Electrohydraulic servo cylinder installing space and
Connecting rod (4) space, it is ensured that Electrohydraulic servo cylinder drives branch bar to slide by connecting rod (4) under the control of digital control computer
Seat (1) is in vertical motion and realizes altitude location.
Technique effect
The purpose of this utility model is to provide for a kind of new positioner, to improve the positioner life-span.With it is existing
Technology is compared, and structure is slightly more complex, still, and the positioner life-span is at least higher than the life-span of the device of existing localization method 5 times, together
When, the height of branch piece be adjusted to it is digital control, it is more convenient and swift than existing method.

Embodiment
Branch bar is designed and fabricated as branch bar fixed seat and branch bar sliding seat, branch bar sliding seat is used to install branch
Piece simultaneously can produce movement in vertical direction with fixed seat, and branch bar fixed seat is used to fix branch bar in screw-rolling machine frame, it is ensured that
The movement in vertical direction of sliding seat.Branch bar sliding seat is provided with branch piece installation site and fastener；Branch bar fixed seat is provided with
Electrohydraulic servo cylinder installing space and link motion space, it is ensured that Electrohydraulic servo cylinder is by connecting rod under the control of digital control computer
Driving sliding seat is in vertical motion and realizes altitude location.
For example：The screw thread of M12 × 1.75 is rolled, Major Diam d is 12mm, and rolled thread blank diameter d0 is 10.84mm, and tooth is high
Increase (12-10.84)/2=0.58mm, rolling speed is 30/minute (2s), is computed, the initial position of branch piece is
Distance is at 5.42mm below cylindrical die roll axial line plane, rolled thread start after with average 0.29mm/s (0.58mm/2s) speed
Move down, be finally stopped below cylindrical die roll axial line plane at 6mm, branch piece moves 0.58mm altogether.Above-mentioned parameter is defeated
Enter digital control computer, and other data realize linkage with screw-rolling machine.After rolled thread starts, by computer according to above-mentioned parameter
Control Electrohydraulic servo cylinder driving sliding seat is in vertical motion, and branch piece locating surface keeps workpiece axial line to be located at sliding seat motion
In cylindrical die roll axial line plane, to reduce the frictional force of workpiece and branch piece locating surface, reduce the abrasion of branch piece, to improve the branch piece longevity
Life.
